What size populations do you typically use?

So it's better to have some small populations (using the same object), than one large area. And what I always do, is place the pop center from a top view a certain distance in front of the camera, taking the size in consideration, and then changing the angle of the pop to the same as the camera's angle. Doing it so that the lower bounding box' line is near the camera's location. That makes the perfect smallest bounding box.

I see a feature request here: "use camera angle" checkbox with camera selection field. (in population node)

The populator already has an option called "clip to camera", but you can't choose which camera to clip to and it always uses the current render camera. But, again, as with density shaders, the terrain displacement needs to be sampled for every *candidate* instance to find out whether it falls within the camera's view.
